Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Derivaten des Hexahydrotriazins der Formel in der X SO2 bzw. C = 0 bedeutet und mindestens ein, vorzugsweise mindestens zwei Reste R die Gruppe darstellt, die übrigen Reste aber auch - CH = CH2 sein können. Hal bedeutet Brom oder vorzugsweiseChlor.It is known that dienes react with certain unsaturated compounds according to 0. Diels and K. Alder, Liebigs Ann. Chem., 460 (1928), 98, can be implemented. The invention relates to a process for the preparation of derivatives of hexahydrotriazine of the formula in which X is SO2 or C = 0 and at least one, preferably at least two, radicals R is the group represents, but the remaining radicals can also be - CH = CH2. Hal means bromine or preferably chlorine.

Als Hexahalogencyclopentadiene seien z. B. das Hexabromcyclopentadien und das Dibromtetrachlorcyclopentadien, vor allem aber das Hexachlorcyclopentadien genannt. Die Umsetzung mit mindestens 3 Mol Hexahalogencyclopentadien ist bevorzugt, jedoch ist auch die Anwendung eines Überschusses, z. B. 6 Mol, möglich. Auch Gemische mehrerer Hexahalogencyclopentadienderivate können verwendet werden.These compounds are obtained by reacting s-hexahydrotriazine derivatives of the formula in which X has the meaning given, with at least 1 mole of hexahalogencyclopentadiene, in which the halogen has an atomic weight of at least 35 and at most 80 at a temperature of 80 to 2500 C in an inert solvent. As Hexahalogencyclopentadien z. B. the hexabromocyclopentadiene and the dibromotetrachlorocyclopentadiene, but especially the hexachlorocyclopentadiene called. The reaction with at least 3 moles of hexahalogencyclopentadiene is preferred, but the use of an excess, e.g. B. 6 moles, possible. Mixtures of several hexahalogencyclopentadiene derivatives can also be used.
Zweckmäßig wird eine Lösung der Reaktionspartner in einem inerten organischen Lösungsmittel in Gegenwart eines Polymerisationsinhibitors, gegebenenfalls unter erhöhtem Druck erhitzt, vorzugsweise auf eine Temperatur von 90 bis 160"C. Geeignete Lösungsmittel sind z. B. Kohlenwasserstoffe, Äther, Ketone, Ester, Alkohole aliphatischer Natur, aromatische Kohlenwasserstoffe oder halogenierte aromatische oder aliphatische Kohlenwasserstoffe, wie Lackbenzin, n-Propanol, iso-Butanol, Toluol, Xylol, Mono- und Dichlorbenzol, l-Chlordekan. Die s-Hexahydrotriazinderivate scheiden sich gegen Ende der Reaktion in kristalliner Form ab oder lassen sich nach Abdestillation des Lösungsmittels durch Zusatz von z. B. A solution of the reactants in an inert one is expedient organic solvent in the presence of a polymerization inhibitor, if appropriate heated under increased pressure, preferably to a temperature of 90 to 160 "C. Suitable solvents are e.g. B. hydrocarbons, ethers, ketones, esters, alcohols aliphatic in nature, aromatic hydrocarbons or halogenated aromatic or aliphatic hydrocarbons such as mineral spirits, n-propanol, iso-butanol, toluene, Xylene, mono- and dichlorobenzene, l-chlorodecane. The s-hexahydrotriazine derivatives divide towards the end of the reaction in crystalline form or can be removed after distillation the solvent by adding z. B.
Petroläther in kristalliner Form abscheiden, je nach- dem, welches Lösungsmittel bei der Umsetzung verwendet wird. Der Polymerisationsinhibitor wird in der üblichen Menge, z. B. von 0,005 bis 0,3 0/,, bezogen auf das Gewicht der Reaktionsteilnehmer, verwendet.Separate petroleum ether in crystalline form, depending on the the which Solvent is used in the reaction. The polymerization inhibitor will in the usual amount, e.g. B. from 0.005 to 0.3 0 / ,, based on the weight of the Respondent, used.
Geeignete Verbindungen sind z. B. Hydrochinon, Mono- und Di-tert.-butyl-hydrochinon, tert.-Butylbrenzkatechin.Suitable compounds are e.g. B. hydroquinone, mono- and di-tert-butyl-hydroquinone, tert-butyl catechol.
Die erfindungsgemäß erhaltenen s-Triazinderivate sind neu. Sie können z. B. als Fungizide oder Insektizide oder als Flammschutzmittel, z. B. für Phenolharze, Epoxyharze, Thermoplasten oder cellulosehaltige Materialien Verwendung finden. The s-triazine derivatives obtained according to the invention are new. You can z. B. as fungicides or insecticides or as flame retardants, e.g. B. for phenolic resins, Find epoxy resins, thermoplastics or cellulosic materials use.
Aus der deutschen Auslegeschrift 1 182 810 ist Tri-(dibrompropionyl)-s-hexahydrotriazin als fiammwidriger Zusatz zu Thermoplasten bekannt. Die Erfahren hat jedoch gelehrt, daß sich die Verwendung dieser Verbindung in härtbaren Formmassen bei der Herstellung von Formkörpern in Eisenformen nachteilig auswirkt, indem zuweilen Verfärbungen der Formkörper auftreten. Diese Schwierigkeiten sind durch die erfindungsgemäß erhältlichen Zusätze behoben. Die Schmelzpunkte der erhaltenen Verbindungen liegen wesentlich höher als die der Vergleichsverbindung, so daß ein unerwünschtes Verdampfen oder Ausschwitzen dieser Substanzen bei Erhitzen bzw. From the German Auslegeschrift 1 182 810 is tri- (dibromopropionyl) -s-hexahydrotriazine known as a flame retardant additive to thermoplastics. However, the experienced has taught that the use of this compound in curable molding compositions in the production of moldings in iron molds has a detrimental effect by sometimes discoloration the shaped body occur. These difficulties are due to the inventively obtainable Fixed additions. The melting points of the compounds obtained are substantial higher than that of the comparison compound, so that undesirable evaporation or Exudation of these substances when heated or
Verformen von Mischungen, die diese enthalten, weit weniger auftreten kann als bei der Vergleichssubstanz.Deformation of mixtures containing these occur far less can than the reference substance.
Außerdem enthält z. B. die erfindungsgemäße Verbindung V (Beispiel 4) noch polymerisierbare Gruppen, so daß sie z. B. in ungesättigten Polyesterharzen durch Mischpolymerisation eingebaut wird. Beim Erhitzen von Formmassen aus diesen Harzen können die erfindungsgemäß erhältlichen ilammwidrigen Komponenten infolge ihrer chemischen Bindung nicht mehr herausdiffundieren oder verdampfen. Eine solche chemische Bindung kann das bekannte Bromtriazinderivat infolge seines gesättigten Charakters aber nicht eingehen. Der technische Fortschritt ist daher eindeutig gegeben. Beispiel 1 In einem 2-l-Kolben, der mit Rückflußkühler, Rührwerk, Gaseinleitungsrohr und Thermometer versehen ist, werden unter Einleiten von Kohlendioxyd 100 g 1,3,5-Tris-acryloyl-s-hexahydrotriazin (0,4 Mol) und 327,6 g Hexachlorcyclopentadien (1,2 Mol) in 800 g Xylol in Gegenwart von 0,2 g Hydrochinon unter Rühren 4 Stunden auf 130 bis 140"C erhitzt. Man erhält eine klare Lösung, die im Vakuum vom Lösungsmittel befreit wird. Der gelbliche sirupöse Rückstand wird mit 500 ml Petroläther zum Kristallisieren gebracht. Man erhält 318 g eines kristallinen farblosen Produktes vom Schmelzpunkt 315 bis 318"C, entsprechend 74,4 0/o der Theorie. Nach der Umkristallisation aus Essigester schmilzt die Verbindung bei 319 bis 320"C.In addition, z. B. the compound according to the invention V (Example 4) still polymerizable groups so that they can, for. B. is built into unsaturated polyester resins by copolymerization. When molding compositions made from these resins are heated, the flame-resistant components obtainable according to the invention can no longer diffuse out or evaporate due to their chemical bond. The known bromotriazine derivative cannot enter into such a chemical bond due to its saturated character. The technical progress is therefore clearly given. example 1 In a 2-liter flask equipped with a reflux condenser, stirrer, gas inlet tube and thermometer, 100 g of 1,3,5-tris-acryloyl-s-hexahydrotriazine (0.4 mol) and 327.6 g of hexachlorocyclopentadiene (1.2 mol) in 800 g of xylene in the presence of 0.2 g of hydroquinone are heated for 4 hours at 130 to 140 ° C. with stirring. A clear solution is obtained which is freed from the solvent in vacuo.
